Specification of Letters Patent. Application filed Ianuary'30, 1908.Serial No. 413,399.

Patented March a, 1909.

To all whom it may concern:

Be it known that I, GEORGE WILLIAM CURTIS, a resident of. Cleveland, inthe county of Cuyahoga and State of Ohio, have invented a new and usefulImprovement in Levers; and I do hereby declare the following to be afull, clear, and exact description thereof.

My invention relates to levers and has special reference to the class oflevers provided with a movable dog or. engaging rod thereon.

The object of my such a form of lever as will be light in weight,manufactured and will be strong and durable when in use, as well as onewhich will occupy a small I space, and will not require any machine ber2.

work.

My invention consists, generally stated, in the novel arrangement,construction and combination of parts, as hereinafter more specificallyset forth and described and partlcularly pointed out in the claims.

To enable others skilled in the art to which my invention a ertain's, toconstruct and nseimy im rov ever, I will describe the same more By,referring to the accompanying drawing, 1n which Figure 1 is a sideelevation of my improved lever. Fig. 2 is an edge view of the same. Fig.3 is a cross-section on the line 3 -3 Fig. 1. Fig. 4 is a cross-sectionon the line 4Fig. 1, and looking in the direction of the arrow.

Like symbols of reference herein indicate like parts in each of thefigures of the draw- Asjllustrated in the drawing, 1 represents myimproved lever which is com osed of the main supporting member 2 and .te movable or -.o 2 is ormed om a plate of sheet metal cut to the sizeand shape re uired, and this plate is adapted to be place within and\between suitable dies of a ress in its coldstate and pressed .orstamped at one operation to form the com lete and finished supportingmemhis plate when placed Within the dies is bent up longitudinally andcentrally to form the narrow U or trough shaped supporting member 2having .on its body the flat sides 4 and the curved or rounded portion 5invention is to provide ratmgrmember 3. The main member' connecting thesame, such sides having their edges 6 formed on a ta er or inclinedinwardly, as at 7, toward t e up er and of the same from the curved orroun ed connecting point 8 for the member 3, as hereinafter described,and such upper end side edges are outwardly flared, as at 9, as well asthe rounded portion 5, as at 10, to form the handle 11 above theflatsided body having the curved or rounded upper end 11 on said sides. Thelower end of the edges 6 on the sides 4 is formed on a taper or inclinedin Wardly, as at 12 from the rounded or curved point 8 and terminates inthe curved lower end 13 which connects with the rounded .or tion 5.After the member 2 has been hus formed to sha e the holes 14 arepunchedor drilled throug the sides 4 for the reception of the pin 15 forsupporting the lower pol? tion of the. member 3 at the connecting point8, and holes 16 and 17 are punched or drilled through said sides for thereception of the pins '18 and 19 for the connecting of the spring forthe member 3 and handle for the same, as hereinafter described. Holes 20are also punched or drilled through the sides 4 and within'the curvedlower end 13 for the reception of a stud or pin 21 which passes througha standard 22 for the pivoting of the member 2 therein. A slot orelongatedhole 23 is punched through the rounded portion 5 0n the member2 and at the lower end of the same for the insertion of a uadrant 24through the same and between t e sides 4 of said member.

The handle 25 for the member 3 is formed from a plate of sheet metal,cut to size and shape re uired, and this late is ada ted to be placewithin and be Ween suita 1e dies of a-press in its cold state andpressed or stamped at one operation to form the complete and finishedhandle. ThlS plate when placed within the dies is bent up longitudi- U-or trough shaped handle 25 for fitting within the handle 11, having itssides and end outwardly flaring as at 26 and 27 respectively and theupper ends of the side many and centrally to form substant1ally a wedges of said sides 26 are curved or rounded to said end 27, as at 28.Lugs or projections 29 having curved or rounded ends extend out from thelower end 0f the side ed es 26 on the handle;25 and connect with thelower end edges on said handle which ends 27 on the same.

The movable or operating member '3 is formed from a late of sheet metaland cut to the size and shape re uired having the tapered or inclinedside e ges 35 extending inwardly from its lower to its up er end. Thismember 3 is adapted to fit within the member 2 and is connected theretothrough the rounded or curved aslot 36 punched or drilled inthe same andfit- I 15 andits lower end has a shoulder 37 formed on its outer sideedge 35 so that said end can engage with the notches 24 in the quadrant24. The upper end of the member 3 is split, as at 38, and rounded orcurved, as at 39, so that said split ends can fit around the handle 25and be connected thereto throu h a in 40 passing through holes 41P11110l1601 rilled n said ends and member. v

A rod 42 can be connected to the member 2 and to the object to'be movedby the lever 1 throu h a pin 43 passing throu h punched or drille holes44 in the sides 4 0 said member and the forked end 45 on said rodfitting around said sides.

With the parts of my improved lever 1 assembled an connected together asshown, eration and use and by pressing the han e 25 toward and aroundthe handle 11 on its pivot pin 19 in the member 2 the mevable member 3connected to said handle 25 through and within the sup 2 and free'itslower end rom its engaging notch 24 in the quadrant 24, such member 3sliding on the pin 15 in the member 3' through the slot 36 and exortingmember tending the spring 33 connecting said handle 25 and said member.2.

Upon the releasing of said handle 25 the tension on the sprin 33 will bereleased and allow the said han e to be thrown away 11, as well aspermitting the lowering of'the member 3 to allow the lower end of saidmember to again engage one of the notches 24 1n the quadrant 24. Bythese operations,
